Question 1 scenario: an analyst wants to test the hypothesis that the percentage of homeowners in the us population is 75%. in order to test this hypothesis she collects data from all over the country your task is to help the analyst perform her hypothesis test. in order to do this you need to compute various statistics using excel. use sm level of significance iscenario 1: ou the percentage of home owners in the us sample is 9 064 154 0.66 0.75
50 apartments were randomly chosen by our pupils. We found 26 residences with owners. We could use this to determine our sample proportion, by the way. It will come out to 26 out of 50 and.52. We're going to conduct an experiment to test the hypothesis that your neighborhood's owner-occupied home percentage differs from the national average.
The null hypothesis will be the outcome of the test. The null hypothesis states that 69 is the actual proportion. The alternative is an alternate theory. We are endeavoring to determine whether the community is different from the country, per the inquiry. I'll concede that the actual ratio is not 0.69. It is necessary to find the test statistic. We are permitted to utilize the calculator function in the tests because this is an example Z test. Yes, a window. We could locate the single proportion Z if we went to the tests and clicked the stat. It's basically a test. The Christmas component cost 69 dollars. Out of 50 samples, 26 have resulted in success.
In our alternative, the true percentage is different from.69, therefore proportion does not equal zero proportion. A negative Z score of 2.599 will be the outcome in the end. The window gives us a p value of 9. We'll choose a resolution. We will compare the p value to our significance level. It doesn't specify the degree of relevance for this problem. We'll only use 5%. So, if our p value is less than the significance level, we would reject the null hypothesis, right? The sample proportion must be obtained. If the null hypothesis is true, it would be extremely rare, since our community has more owner-occupied homes than the national average, according to the data.

you have a 10 mile one way distance to commute to work. the cost of your travel time is $60/hour. weather is not a factor. which mode should you use to commute?
Driving a personal car would be the most cost-effective mode of transportation for this commute, with a total daily cost of approximately $4.60 ($3.60 for gas + $1 for travel time).
Based on the given information, the most cost-effective mode of transportation for this commute would be to drive a personal car. Taking public transportation or carpooling may be more environmentally friendly options, but they may not save as much money as driving alone.
Assuming an average speed of 60 miles per hour on the highway, the commute would take approximately 20 minutes each way, or 40 minutes round-trip. This means the total cost of travel time for each workday would be $40 ($60/hour x 2/3 hour).
Using a cost calculator such as GasBuddy, we can estimate that the cost of driving 20 miles per day (round-trip) would be around $3.60 per day, assuming an average fuel efficiency of 25 miles per gallon and a gasoline price of $2.50 per gallon.

The weight of a randomly selected party size bag of tortilla chips coming off an assembly line is normally distributed with mean = 16.3 ounces and standard deviation = 0.2 ounces. Suppose we pick 4 bags at random and the sample mean = 16.26. The actual sampling error is __________ and the typical sampling error is __________.
The weight of a randomly selected party size bag of tortilla chips coming off an assembly line is normally distributed with mean = 16.3 ounces and standard deviation = 0.2 ounces. Suppose we pick 4 bags at random and the sample mean = 16.26. The actual sampling error is 0.04 ounces and the typical sampling error is 0.05 ounces.
What is sampling error? The difference between a population parameter and its corresponding sample statistic is known as sampling error. It's also called estimation error. Sampling error can occur in any type of experiment or study when a sample of data is used to estimate a population's parameters or characteristics. The greater the sample size, the smaller the sampling error; the smaller the sample size, the greater the sampling error.
The sampling error formula is:
Sampling error = sample statistic - population parameter.
What is the actual sampling error?
To compute the actual sampling error, we use the formula:
Actual Sampling Error = Sample Mean - Population Mean.
Given the data we have, Sample Mean = 16.26Population Mean = 16.3
Actual Sampling Error = 16.26 - 16.3= -0.04.
Therefore, the actual sampling error is -0.04 ounces.
What is a typical sampling error? We use the formula below to compute the typical sampling error.
Typical Sampling Error = Standard Deviation / √(Sample Size)Standard deviation = 0.2 ounces
Sample size = 4 bags
Typical Sampling Error = 0.2/√4= 0.1/2= 0.05
Therefore, the typical sampling error is 0.05 ounces.

make a list of some of the challenges when reading a text containing historical content.
Reading a text containing historical content can present several challenges, including unfamiliar vocabulary, cultural context, biased perspectives, interpretation of primary sources, and navigating different historical periods.
One of the challenges when reading historical texts is encountering unfamiliar vocabulary and terminology that may be specific to the time period being discussed. Historical texts often use language and terms that may have different meanings or have fallen out of common usage. Another challenge is understanding the cultural context in which the events took place. Cultural norms, beliefs, and social structures of the past can be different from our present understanding, requiring readers to research and gain insight into the historical context.
Additionally, historical texts can present biased perspectives or reflect the prevailing ideologies of the time, which may require readers to critically analyze the information and consider alternative viewpoints. Interpreting primary sources, such as diaries, letters, or official documents, can be challenging due to the potential for bias, subjective viewpoints, and the need to cross-reference multiple sources.
Furthermore, navigating different historical periods and understanding the chronology of events can be complex, especially when reading texts that span different time periods or discuss historical events out of sequence. It requires readers to have a solid understanding of historical timelines and the interconnectedness of events to grasp the full context of the text.

an adult dolphin weighs about 1800 n. with what speed i must he be moving as he leaves the water in order to jump to a height of 2.10 m. ignore any effects due to air resistance.
Given information: Mass of dolphin, m = 1800 N; Height of jump, h = 2.10 m.
The gravitational potential energy of the dolphin can be calculated as follows: Gravitational potential energy = mgh where, m is the mass of the dolphin, g is the acceleration due to gravity, and h is the height of the jump.
Given that the dolphin jumps from the water, its initial potential energy is zero. Hence, the total energy of the dolphin is equal to the potential energy at the highest point. At this point, the kinetic energy of the dolphin is also zero. Therefore, the energy conservation equation can be written as follows: mg h = (1/2)mv²where, v is the velocity of the dolphin just before it jumps out of the water.
Solving for v, we get v = sqrt(2gh)where sqrt denotes the square root, g is the acceleration due to gravity, and h is the height of the jump. Substituting the given values, we get v = sqrt(2 x 9.8 x 2.10)v = 6.22 m/s Therefore, the dolphin must be moving at a speed of 6.22 m/s as it leaves the water in order to jump to a height of 2.10 m.

as shown below the tank will have a height if 2 ft and a diameter of 14 ft the tank we be made of metal. if the metal costs $22 for each square foot . how much will the metal cost in total
Using the surface area, the cost value for metal is obtained as $8,707.68.
What is surface area?
The area is the area occupied by a two-dimensional flat surface. It has a square unit of measurement. The surface area of a three-dimensional object is the space taken up by its outer surface. Square units are used to measure it as well.
To find the surface area of the tank, we need to find the area of the circular top and bottom, and the area of the cylinder.
The area of a circle is given by: A = πr², where r is the radius.
Since the diameter is given as 14 feet, the radius is 7 feet.
So, the area of the top and bottom circles is: A1 = π(7²) = 153.94 square feet (rounded to two decimal places).
The circumference of the circular base is given by: C = πd, where d is the diameter.
So, the circumference is: C = π(14) = 43.98 feet.
The height of the cylinder is given as 2 feet, and the circumference of the base is 43.98 feet.
So, the area of the curved surface of the cylinder is -
A2 = C × h
A2 = 43.98 × 2
A2 = 87.96 square feet (rounded to two decimal places).
Therefore, the total surface area of the tank is -
A = 2A1 + A2
A = 2(153.94) + 87.96
A = 395.84 square feet (rounded to two decimal places).
The cost of the metal per square foot is given as $22.
So, the total cost of the metal is -
Cost = Area × Cost per square foot
Cost = 395.84 × 22
Cost = $8,707.68.
Therefore, the metal will cost $8,707.68 in total.

A loan is made for $4800 with an APR of 12% and payments made monthly for 24 months. What is the payment amount? What is the finance charge?
The monthly payment amount is $217.42 and the finance charge is $413.02.
The payment amount and finance charge can be found by using the formula below
Payment amount formula: PMT = (P x R x (1 + R)^N) / ((1 + R)^N - 1)
Finance charge formula: Finance charge = Total payment - Loan amount
Where P = Loan amount
R = Interest rate per period
N = Number of periods
Given that a loan is made for $4800 with an APR of 12% and payments made monthly for 24 months
Therefore,P = $4800R = 12% / 12 = 1% per month
N = 24
Using the Payment amount formula above: PMT = (P x R x (1 + R)^N) / ((1 + R)^N - 1)
PMT = ($4800 x 0.01 x (1 + 0.01)^24) / ((1 + 0.01)^24 - 1)
PMT = $217.42
Hence, the monthly payment amount is $217.42 (rounded to two decimal places).
Using the finance charge formula above: Finance charge = Total payment - Loan amount
Total payment = Payment amount x Number of periods
Total payment = $217.42 x 24 = $5213.02
Finance charge = $5213.02 - $4800
Finance charge = $413.02
Hence, the finance charge is $413.02 (rounded to two decimal places).

. solve recurrence relation using any one method: find the time complexity of the recurrence relations given below using any one of the three methods discussed in the module. assume base case t(0)
Recurrence relations are mathematical equations that define the running time of an algorithm in terms of its input size. To find the time complexity of a recurrence relation, we can use one of the three methods: substitution method, recursion tree method, and master theorem.
The substitution method involves replacing the recurrence relation with an assumed solution and then proving it using mathematical induction. The recursion tree method involves constructing a tree diagram to represent the recurrence relation and calculating its running time. The master theorem is a formula that can be used to determine the time complexity of a recurrence relation based on its coefficients.
Assuming the base case t(0), we can find the time complexity of a recurrence relation using any of these methods. For example, if we have a recurrence relation of the form T(n) = 2T(n/2) + n, we can use the master theorem to find its time complexity. The theorem states that if the recurrence relation is of the form T(n) = aT(n/b) + f(n), where a >= 1, b > 1, and f(n) is a polynomial, then its time complexity is O(nlogba) if logba > c, O(nlogba log n) if logba = c, and O(n^c) if logba < c, where c is a constant.
In summary, to find the time complexity of a recurrence relation, we can use one of the three methods: substitution method, recursion tree method, and master theorem. All three methods involve solving the recurrence relation and determining its running time based on its input size.

The converse of the statement "If a figure is a square, its diagonals divide it into isosceles triangles" would be:
"If a figure's diagonals divide it into isosceles triangles, then the figure is a square."
The converse statement is not necessarily true. While it is true that in a square, the diagonals divide it into isosceles triangles, the converse does not hold. There are other shapes, such as rectangles and rhombuses, whose diagonals also divide them into isosceles triangles, but they are not squares. Therefore, the converse of the statement is not always true.
Therefore, the converse of the given statement is not true. The existence of diagonals dividing a figure into isosceles triangles does not guarantee that the figure is a square. It is possible for other shapes to exhibit this property as well.
